Rain-erosion resistant optical component

摘要

Optical component (5) comprising a substrate (6) of a material having a predetermined rate of transmission of radiation having a wavelength within a predetermined band of wavelengths, and a coating (7) extending over a surface (6 ') of the substrate (6). The coating (7) comprises a matrix (8) based on at least one polymer in which nanoparticles (9) are embedded, the optical component (5) having in total a transmission rate sufficient for the application for lengths. of waves included in the predetermined band of wavelengths.
